In which direction did technology change education in the story?

Correct answer: From group school to private home study

The story contrasts two kinds of education. In the future world, children study alone at home with a mechanical teacher. In the earlier system, children went to a school building, met classmates, and learned together under a human teacher. Thus, technology changed education from group schooling to individual home study. The important idea is not simply that a machine was used, but that learning became isolated and separated from ordinary social interaction.

Margie and Tommy find an old printed book and are surprised that children once studied together. Their lessons are delivered by machines in their own homes, so option A correctly describes the direction of change. Option B concerns play, option C reverses the development shown in the story, and option D is not what happens. The choice highlights the loss of shared classroom experience.
